By default, it should not be exported, but a user could export it themselves. How about a double check of RANDOM? If it gets exported, the inherited value in (a)sh appears to be constant, while in bash it changes with each access. The only problem I can see with this is that a user could unset RANDOM, then make a new variable with that name, but which will not have the special feature. I would think that this is rare enough to maybe be ignored? -- Bob McGowan Staff Software Quality Engineer VERITAS Software rmcgowan AT veritas DOT com -- Want to unsubscribe from this list?
